can: flexcan: fix flexcan driver build for big endian on ARM and little endian on PowerPc

2014-01-29T19:23:22Z

There is no reason to disallow building the driver on big-endian ARM kernels. Furthermore, the current behavior is actually broken on little-endian PowerPC as well. The choice of register accessor functions must purely depend on the CPU architecture, not which endianess the CPU is running on. Note that we nowadays allow both big-endian ARM and little-endian PowerPC kernels. With this patch applied, we will do the right thing in all four combinations.

can: Disable flexcan driver build for big endian CPU on ARM

Building arm:allmodconfig fails with flexcan.c: In function 'flexcan_read': flexcan.c:243:2: error: implicit declaration of function 'in_be32' flexcan.c: In function 'flexcan_write': flexcan.c:248:2: error: implicit declaration of function 'out_be32' in_be32 and out_be32 do not (or no longer) exist for ARM targets.

can: ti_hecc: Replace platform dependency with ARM dependency

2013-12-21T23:03:51Z

OMAP's ti_hecc driver is used to support the CAN controller on many omap2plus SoCs (OMAP2430, OMAP3, OMAP4, OMAP5 and AM335x), so it's wrong to make this depend on OMAP3 only. Take an extra step, to get wider build coverage, and make the driver depend on ARM. Signed-off-by: Ezequiel Garcia Signed-off-by: Marc Kleine-Budde

can: flexcan: remove HAVE_CAN_FLEXCAN Kconfig symbol

2013-06-03T11:13:49Z

This patch removes the Kconfig symbol HAVE_CAN_FLEXCAN from arch/{arm,powerpc} and allowing compilation unconditionally on all arm and powerpc platforms. This brings a bigger compile time coverage and removes the following dependency warning found by Arnd Bergmann: warning: (SOC_IMX28 && SOC_IMX25 && SOC_IMX35 && IMX_HAVE_PLATFORM_FLEXCAN && SOC_IMX53 && SOC_IMX6Q) selects HAVE_CAN_FLEXCAN which has unmet direct dependencies (NET && CAN && CAN_DEV) Acked-by: Arnd Bergmann Acked-by: Benjamin Herrenschmidt Acked-by: Shawn Guo Signed-off-by: Marc Kleine-Budde

can: Kconfig: CAN_AT91 depends on ARM

2013-03-27T12:07:08Z

SAMA5D3 devices also embed CAN feature. Moreover if we want to produce a single kernel image it is not useful to be too restrictive. Signed-off-by: Ludovic Desroches Signed-off-by: Marc Kleine-Budde

can: add tx/rx LED trigger support

2013-01-26T15:58:59Z

This patch implements the functions to add two LED triggers, named -tx and -rx, to a canbus device driver. Triggers are called from specific handlers by each CAN device driver and can be disabled altogether with a Kconfig option. The implementation keeps the LED on when the interface is UP and blinks the LED on network activity at a configurable rate. This only supports can-dev based drivers, as it uses some support field in the can_priv structure. Supported drivers should call devm_can_led_init() and can_led_event() as needed. Cleanup is handled automatically by devres, so no *_exit function is needed. Supported events are: - CAN_LED_EVENT_OPEN: turn on tx/rx LEDs - CAN_LED_EVENT_STOP: turn off tx/rx LEDs - CAN_LED_EVENT_TX: trigger tx LED blink - CAN_LED_EVENT_RX: trigger tx LED blink Cc: Wolfgang Grandegger Cc: Marc Kleine-Budde Signed-off-by: Fabio Baltieri Acked-by: Oliver Hartkopp Signed-off-by: Marc Kleine-Budde

can: Kconfig: convert 'depends on CAN_DEV' into 'if CAN_DEV...endif' block

2013-01-26T15:58:58Z

This patch adds an 'if CAN_DEV...endif' Block around the CAN driver symbols in drivers/net/can/Kconfig. So the 'depends on CAN' dependencies can be removed. Signed-off-by: Marc Kleine-Budde

tty: Added a CONFIG_TTY option to allow removal of TTY

2013-01-19T00:15:27Z

The option allows you to remove TTY and compile without errors. This saves space on systems that won't support TTY interfaces anyway. bloat-o-meter output is below. The bulk of this patch consists of Kconfig changes adding "depends on TTY" to various serial devices and similar drivers that require the TTY layer. Ideally, these dependencies would occur on a common intermediate symbol such as SERIO, but most drivers "select SERIO" rather than "depends on SERIO", and "select" does not respect dependencies. bloat-o-meter output comparing our previous minimal to new minimal by removing TTY. The list is filtered to not show removed entries with awk '$3 != "-"' as the list was very long. add/remove: 0/226 grow/shrink: 2/14 up/down: 6/-35356 (-35350) function old new delta chr_dev_init 166 170 +4 allow_signal 80 82 +2 static.__warned 143 142 -1 disallow_signal 63 62 -1 __set_special_pids 95 94 -1 unregister_console 126 121 -5 start_kernel 546 541 -5 register_console 593 588 -5 copy_from_user 45 40 -5 sys_setsid 128 120 -8 sys_vhangup 32 19 -13 do_exit 1543 1526 -17 bitmap_zero 60 40 -20 arch_local_irq_save 137 117 -20 release_task 674 652 -22 static.spin_unlock_irqrestore 308 260 -48 Signed-off-by: Joe Millenbach Reviewed-by: Jamey Sharp Reviewed-by: Josh Triplett Signed-off-by: Greg Kroah-Hartman
